I highly recommend esphome if it covers your use case. And MQTT can be implemented in esphome if you prefer that

I tried hooking up a usb solar panel to the esp Xiao with the grove breakout and a battery and it worked for a time and then promptly burned up my Xiao. It definitely needs a dedicated charging board in between. #Meshtastic

Had a great time at VCFMW a convention I did not actually know about until I heard about it over the meshtastic mesh!

The first meshtastic box for my car is complete. I am trying to decide if it is worth the work of mounting the antenna on the outside of the car or if I just accept the signal attenuation. I will probably have to do a range test to decide.

Fell down the meshtastic rabbit hole and now I may need to get HAM certified. Loving the seeedstudio products and I with their radios were not always on backorder.

Upon reading more I really thought I2S had more in common with I2C but turns out it does not. I2S is still a good protocol and there are probably boards that can bridge the gap between i2C or usb

If you have I2C access available there is a protocol called I2S that is specifically for audio.

Curious how to set up OTA firmware updates for ESP32 using Rust and Harbor as an OCI registry? Built with MQTT over TLS, minimal backend, and #RustLang. Full post on secure IoT + #OTA + #ESP32 + #oras + #Harbor + #Kubernetes

Rust for IoT: Building a Secure ESP32 Weather Sensor with MQTT, TLS, and OTA Updates

During downtime between freelance projects, I often use the time to learn new things. This time, I explored the world of IoT and built a weather sensor with an ESP32 board, then decided to document th...

Having tried both which do you prefer between the influx dashboards and graphana?

This is fantastic. I have been doing something similar but this just has such a nice tech stack all put together. I had no clue cargo existed and this will a good push to try rust.

These are absolutely fantastic, 3D printed aids helped tremendously in my physical chemistry classes and these take it to the next level.

After building these bookshelves nearly a year ago I promised I would make decorative column toppers for them. I finally got around to designing them in blender and getting them printed and painted. #3DPrinting

Here is another one I made for the #cyberpunk vibe. An air quality monitor built into a respirator. Since it reports particle counts and VOC you always know what filters to use with it. Electronics are all #M5 stack atom along with an I2C display. #electronics

I did this build a year or two ago because I was captivated by the cyberpunk aesthetic. Raspberry Pi laptop, I regret the narrow screen too many things have a fixed window size and it doesn't show nearly enough terminal for general use but it does look good. www.hackerspace-ffm.de/wiki/index.p...

I would really recommend getting your buck converter up off the bottom. It looks pretty lush where you are at and condensation may pool in your case and short out your board. Super clean build and very cool. I might build one myself!

Why not just cut out the chip and tape it onto third party spools. At least the ones on the Bambu ams are just RFID so I have seen people order normal sunlu filament of the same color and just reuse the chip.

This is super cool! Is it particularly loud at all? I always see the spinning hologram things but as cool as they look I imagine they sound like a helicopter. I bet the enclosure helps a lot.

After years of hacking together Arduino code from online I finally started in earnest to learn microcontroller programming and wrote my first blinky in assembly. I'm following a YouTube series by Brock LaMeres, he is a great speaker and easy to learn from.

Recently made a 3D printed ball vice to help my sister paint models. Can be found for free. Pretty good build all around. Having the model so I can make new things for the base is great. The creator Chris Borge really has some impressive stuff.

I am hoping to use this account to highlight the projects that I do and attract like minded people.
